DEVELOPMENT OF MODELS FOR DESCRIBING THE PROCESSING OF ENVIRONMENTAL INFORMATION IN SECURITY PROBLEMS OF CONTROLLING A PROTECTION SYSTEM BASED ON PETRI NETS

The study is devoted to the description of the protection system as a set of applications based on the Petri net. The main difficulty in managing the safety of such systems lies in the processing of a large amount of environmental information about the state of the object, possible threats and the formation of management actions. This article proposes the use of Petri nets to describe the processes of processing environmental information during the functioning of the elements of the protection system. The structural-logical model of the system is presented as a hypergraph. The elements of the structural-logical model of the protection system are presented in the form of control points (CP). Which are divided according to their functions: detection point (DP), access point (AP), observation point (OP), delay point (DeP) and controls represented by authorization and authentication managers (AzM, AcM). Models for environmental information processing of the following elements of the protection system have been developed: abnormal motion analyzer, logical manager, general manager, universal control unit.
